TERMS TO KNOW
  • Null Hypothesis with Two Samples

    A claim about a population difference that serves as the starting assumption for a hypothesis test. The null hypothesis usually tests that the difference in a certain parameter between two samples, such as a mean or standard deviation, is equal to zero.

  • Alternative Hypothesis with Two Samples

    A claim that there is a difference in a population parameter between two samples. The alternative hypothesis is always an inequality statement.
